Description Massachusetts Institute of Technology

The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head. Although there are several other types of milling machines, this document will focus only on the vertical milling machine. A milling machine removes metal by rotating a multi-toothed cutter that is fed into the moving workpiece.

Electron Beam an overviewScienceDirect Topics

Electron beam machining (EBM) had been used in aerospace and nuclear industry since 1960 for welding applications. EBM is also used for microdrilling, cutting, and engraving applications. In a vacuum chamber a tungsten cathode filament is heated to between 2500 and 3000 °C to emit electrons, which are focused by a magnetic or static lens system to the workpiece specimen, over a well-defined

What is Electron Beam Welding? Process Definition and

Electron beam (EB) welding is a fusion welding process whereby electrons are generated by an electron gun and accelerated to high speeds using electrical fields. This high speed stream of electrons is tightly focused using magnetic fields and applied to the materials to be joined. The beam of electrons creates kinetic heat as it impacts with the workpieces, causing them to melt and bond together.
